Hi all, been browsing the forum here and decided it was time to register. Years ago I had an old pot-belly coal stove, and it did a nice job keeping my (then) house warm.

So fast-forward to 2013, I have a late 1920's brick home (two story) and have been burning oil for years. Now, it's time to do something about that... last bill was nearly $800... that is one of four fillups I get per year.

The house has cast-iron HW radiators which do a good job of distributing the heat. I have a 155,000 BTU/HR Columbia boiler in the basement.

Because I already have the oil-burner in the basement, I think a stoker boiler is the right way to go. I am in my early 50's and don't want to have to tend to the stove every day... I would like something that can run for 3 days without having to be refilled or ashes emptied.

I think I will go with the DHW coil which should save me additional money (propane) during the heating months.

I had the local Harmon dealer come out. Looked things over but not very familiar with the VF-3000 model. I think I read that these are a little different animal than what the Harmon dealers normally sell?

So I am looking for suggestions and recommendations. Some info which I think will help, in no particular order- I have multiple basement windows so delivery via chute would be simple. I can build a bin in the corner of the basement closest to the road, though this is farthest away from the boiler location- As I said, my current boiler is rated at 155,000 BTU/HR but it's been there for years (with annual tune-ups, testing about 85% efficient) and I have done a lot to the house to try and reduce heat loss and infiltration. Attic blanket, insulated the floor over top the basement, new energy efficient vinyl windows, and new storm doors.- Exterior wall construction is two layers of brick, then lathe, and plaster. No wall insulation - The oil burner typically runs maybe once every 2-3 hours when it's 20 to 30 degrees out. I burn between 560 and 600 gallons of fuel per year, historically.- I thought about a direct-vent (like the DVC-500) but don't want to put a hole through the side of the house

I'm sure I will think of more info to post...

The configuration I have in mind right now is:Stoker boiler (such as the VF-3000)DHW coil kitOil burner kit for backupBackup electric kit

I'd pass on the VF3000. They are a nice boiler, but you can get a nice Efm with a wider range of output for about 50% less.

With that said, you are wise to consider a stoker boiler for heat & hot water. My dad and I installed a 50 yr old EFM in his house three years ago. He said it was the best money he ever spent on the house.

Checkout keystoker ka 6 boiler. Very simple design, holds 375 lbs of coal. Has option for dhw coil and oil burner, me personally would pipe it into oil boiler. Keystoker is very quite stoker too. If you add your location in profile, you might get someone to show their setup

Sounds like you are about to make a smart move. The Harman is a good unit, as is the EFM. Our Maryland moderator (coalkirk) has had the Harman for several years and is very happy with the performance. One thing to consider is how much room you have; another is if you want a coal stoker with its own oil burning capability. Many people keep their existing oil burner and plumb in the coal stoker so they can use either.

When looking at the different mfg'ers something to think about.....with Harman's customer service track record and dealer knowledge base, you would probably need to be your own troubleshooter / repairman. With help from this forum of course! Your local harman dealers lack of knowledge should have all kinds of warning sirens going off.

Other companies seem to fare much better based on the comments here and their participation on this forum (see Leisure Line or EFM).

If you want to go 3 days without loading coal / emptying ash you will probably need an auger fed unit from an indoor coal bin. You will need the unit to house a fairly large tub to collect that amount of ash. That tub may get a bit heavy to move around without creating a lot of dust so you may want to have a daily routine to empty it. Available basement space and ease of filling the indoor bin from outside are considerations regarding coal bin and boiler placement.

I installed an EFM last winter. Got it online about half way through the winter. I was using a similar amount of oil, and this winter it looks like I will burn 6 tons of coal. That works out to about half the cost of oil. It is more work since you have to empty out the ashes. I tend to go every other day on that chore until it stays in the 20's. Then it is an everyday chore. I use two smaller tubs, and the weight of the ash is about all I really want to deal with. But that has as much to do with the low ceiling in my basement as anything.

The EFM has been a pleasure. I've had all of two problems, neither of which were the machines fault. Once, a piece of driveway gravel got mixed into the coal and jammed the auger. The shear pin sheared as it was designed to do, and it took all of 30 minutes to get it back online. The second was a stainless steel band got mixed in the coal and wound itself around the auger. Again, 30 minutes and I was back online.

"2ndtimer" welcome to the forum. Send me your phone number via the PM (Private Message) icon on the right. I'll call you and discuss your needs and how to meet them. To others, he lives in the same county as I, and we are likely only tens of miles apart.

Im going to leave the stoker advise to some other here who are experts, but i do have a request if possible... Im interested in the 1920's brick two story also cast iron h/w baseboard is a rare and wonderful thing that has serious value these days! So if you can someday make a thread about your house with some pics of the features like that cast iron baseboard, id really enjoy it! and best wishes on your quest...
